We’re Cooking with Greener Gas

Welcome to ARENA Insights - a newsletter dedicated to sharing knowledge and insights directly with industry.


Forward Insights to a friend

Gas networks get an injection of the future

Jemena’s Western Sydney Green Gas Project is demonstrating the potential role that green gas will play in the transition to a carbon-free energy system. Located in Horsley Park, the project is producing green hydrogen on-site which is injected into the local natural gas distribution network. The project is also investigating green gas applications such as energy storage and power generation. This setup provides a unique opportunity to investigate different use cases and services to identify how green hydrogen can best help accelerate the energy transition.

Crowd-sourcing green gas

Households and businesses in Sydney’s eastern suburbs will soon be cooking with a greener blend of gas thanks to the Jemena Malabar Biomethane Injection Project at Sydney Water’s wastewater treatment plant. This facility already generates large quantities of biogas, which is usually flared or used for power generation. Jemena’s project will involve upgrading the gas to biomethane and then injecting it into the local gas network. According to the project’s Life Cycle Assessment, this would result in 91% emissions reduction compared to the regular gas network. The project will therefore provide a valuable demonstration of how to use an existing resource to help decarbonise sectors reliant on natural gas.

A greener future for regional towns

Wodonga and Ballarat in Victoria, and Port Adelaide in South Australia are the focus of feasibility studies exploring injecting green hydrogen into the local natural gas network. The Australian Hydrogen Centre (AHC) commissioned the studies, which provide a detailed and valuable perspective on the potential role that green hydrogen could play to help decarbonise regional areas.The Wodonga study led to a successful submission to ARENA’s Hydrogen Deployment Funding Round and the project is now progressing towards financial close to build the 10 MW Hydrogen Park Murray Valley project proposed in the study.

Biomethane injections get a booster

Australia has enough biomethane to replace 25% of the natural gas used in Australia's gas pipelines, according to Australia’s Bioenergy Roadmap. In 2022, ARENA supported Bioenergy Australia to commission a study into the benefits of injecting biomethane into natural gas networks to displace conventional gas. Opportunities and priorities are presented, including amending the relevant Australian standard (AS4564).
